CARLINE.

Application filed August 7, 1920. Serial No. 401,842.

To all whom it may concern:

Be it known that l, CHARLES i). BONSALL, a citizen'of the United Stat-es, residino at Parnassus, in the county of lestmoreland and 'State of Pennsylvania, have invented a new and useful Improvement in Cai-lines,

, of which the following is a specification.

This invention relates to improvements in railway car roofs and more particularly to metal carlines for railway box cars.

It is the object of this invention to provide a metal carline pressed from a rectangular sheet oi metal without being trimmed that is strong -and yet light to be used on a car having either metal or wooden side plates. It is also the object of this invention to produce a metal carline in which the metal 1s equally distributed on both sides of the longitudlnal central line of the carline proucing an equal amount of resistance on both sides of the carline to the tendency of the carline to twist due to the end thrusts of the purlins or the racking or weaving of the car.

While the preferred forms of this invention are illustrated upon the accompanying sheet-s 'ofdrawingsg yet it is to be understood that minor detail changes may be made without departing from the scope thereof.

In the drawing:

Figure 1 is a view in side'elevation of a carline embodying one form of this inven tion.

Figure 2 is atop plan view of Figure l.

Figure 3 is an enlarged detail view in section on the line 3 3 of Figure 1.

Figure 4 is an enlarged detail view in section on the line 4-4 of Figure 1.

Figure 5 is an enlarged det-ail view in section on the line 5-5 of Figure 1.

Figure 6 is a view in side elevation of a carline'embodying a modified form of this invention.

Figure 7 is a top plan view of Figure 6. Figure 8 is an enlarged detail view in section on the line 8 8 of Figure 7.

Figure S'is a view in side elevation of a carline embodying another modified form of this invention.

Figure l0 is a. top plan view of Figure 9.

Figure 11 is an enlarged detail section on the line 11 11 of Figure The carline illustrating the Figures 1 to 5 of the drawing is pressed frein a rectanit up portion slope v and Figures 9 in the form of an inverted U extending centrally throughout its length and having a substantially flat top 1, and substantially fiat webs 2 on each side which terminate in substantially fiat horizontal flanges 3. n this iiormof carline the height of the iop 1 of the struck up portion above the Hanges 3 remains constant and parallel to-the plane of the flanges for an equal distance from each end and then increases equally on bot-h sides until adjacent the middle where it again remains constant and parallel to the plane ol the flanges, forming a substantially horizontal portieri. The bottoms of the webs 2 lie in the same horizontal plane and their height increases with the height of top 1, the greatest height boing at the middle portion. The width ot' the rectangular sheet` of metal from which the carline is pressed is such that the webs 2 at the middle, or greatest constant height, terminate in the horizontal plane of the bottom of the carline, as shown in Figure 3. As the height of the top l decreases on each side of this portion the surplus metal in the webs 2 is turned outward into the horizontal flanges 3, the width of which increase uniformly in accordance with the of the top unt-il it reaches the portion of constant height adjacent the ends where the width of the lianges also remain constant. From Figures 3, 4 and 5 it is readily seen that the amount ot' met-al on each side of the longitudinal center line of the carline remainsccnstant throughout its length and each side of the carlinc is equally reinforced by the flanges 8 to resist twisting forces.

The form illustrated in Figures 6, 7 and 8 differs in that the top 10 is transversely curved on the arc of a circle tangent to the webs 20, as shown in Figure 7, and the height ot the top above the plane of the bottom increases constantly on each side from the portions of constant height adjacent the ends until the middle is reached and consequently the webs 20 merge at the middle into the anges 30.

ome cars are provided with acurved roof carline constructed in accordance with this invention to be used in such a roof. In this form the height of the top 100 increases constantly from each end of the carline so that the'top will lie in the arc of a circle parallel to the crown of the roof, therefore, the webs 200 will increase constantly in and 10 illustrate af form ed' height towards the middleI and the flanges 300 will increase constantly in width from the middle to the ends of the carline. The Webs may bc constructed parallel as shown in Figures 3, ul, 5 and 8 or departing from the top'at an angle to each other, as shown in Figure 1l: and the top of the carline may be substantially flat, as shown in Figures l to 5, or formed on the arc of a circle tangent to the web, as shown in Figures 8 and ll., without departing from the spirit of this invention. In the forms illustrated in Figures 6, 7, 9 and l0, the top of the carline at the middle is pressed flat for supporting the ridges ot the roof. A

The means for securing the ends of the carline to the side plates of the car, as shown in Figures l and 2, comprising a Z bar 4 with the end of the carline abutting the web and flanges 3 resting upon and secured to the lower angle and the upper angle extending outward to rest upon and be secured to the side plate. In this form three rivet or bolt holes are provided in the projecting flange of the Z bar. lhere it is desired to provide a greater number of rivets or bolts a Z bar l0 of greater length than the width of the bottom of the carline is provided, as shown in Figures '7 and 10.

What I claim is:

l. A carline comprising a longitudinal portieri ot substantially inverted U section of uniform width with webs on each side terminating in the same horizontal plane and decreasing in height towards each end.

and having flanges in said plane increasing in width towards each end.

2. A earline comprising al longitudinal portion of substantially inverted U section of uniform width and side webs terminating in the same plane throughout their length, the crown of the U extending parallel to the bottom plane a distance from' each end and then increasing in height uniformly on each side towards the middlei the webs turned into flanges lying in the plane of the bottom increasing in width from' thel middle as the crown decreases in height.

3. A carline comprising a central longitudinal portion of substantially inverted U section of. uniform width "from'end to end, the side webs of which terminate at the bottom in the. same horizontal plane, a portion which width decreases in proportion to the increase in height of the crown and the flanges merge into the web as this pointis reached.

4. A carline comprising a longitudinal portion of uniform width of metal having similar depending webs on each side terminating in one and the same longitudinal plane, said webs decreasing in height towards each end and presenting the greatest amount of metal therein to support loads therebetweenand having flanges in said plane increasing in width towards each end.

5. A carline comprising a longitudinal portion of uniform Width of metal having similar depending webs on each side terminating in one and the same'longitudinal plane and decreasing in height towards each end and having flangesV in said,plane increasing in width and presenting the greatest amount of metal therein to resist torsional strains at the ends.

6. A portion of uniform width of metal having similar depending webs presenting an equal amount of metal on each side of the longi-.

tudinal .center line, said webs decreasing in height towards each end and presenting the greatest amount of metal therein to support loads therebetween, and having flanges increasing in Width and presenting the greatest amount of metal therein to resist torsional strains at the ends.

7. A metal carline comprising a longitudinal portion of uniform Width having similar depending Webs turning throughout a portion of their length into similar flanges on each side-of the longitudinal and transversey center lines, maintaining an equal amount of metal on each side of the longitudinal center line irrespective of variations in the height of the webs and presenting a maximum amount otmetal i-n a vertical direction between the flanged portions.
